If you use HADCRUT temperature record for the Southern Hemisphere from 1850 it is possible to discern a peak in 1880, 60 years before the 1940 peak, and 120 years before 2000 when the infamous «global cooling» period, 2002 - 08, kicks in.

Given that there is greater uncertainty associated with the HadCRUT data prior to 1900 due to fewer stations and sparser global coverage, and that the TCR constrained by 1901 - 2000 data better matches the IPCC central TCR estimates, their higher TCR (approximately 1.7 to 2.5 °C) seems more likely to be correct.
